PUMP.

SPECIFICATION forming part of Letters Patent No. 724,048, dated March 31, 1903.

I Application filed May 2,1902. Serial No.105,596 (No model.)

To aZZ whom it @my con/cern:

Be it known that I, HERBERT PERCY SAUN- DERs0N,a subject of the King of Great Britain, residing at Elstow Works, Bedford, in the county of Bedford, England, have invented new and ruseful Improvements in Pumps, of which the following is a specification.

The object of my invention is to construct .a simplepump thatvmay be attachedto the bottom of a tube and lowered down a well until it rests firm on the bottom with or without any further fixing and proceed to pump by working the tubular pump-rod up and down, the water coming up it. The pump is particularly suitableV for Artesiau wells and may also be used for all ordinary purposes and as any other lift and force pump. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a vertical elevation of the pump, part of which is in section. Fig. 2 is a view of the air-chamber that may be inserted between the check-valve'z' and the T Z when'the pump is used for an Artesian well. Fig. 3 is a view of another form of baseplate.

In carrying my invention into practice I construct, as shown by the annexed drawings, a base-plate a or a', of any suitable size, having a universal joint b or b in the center, (or it may be a ball or other free joint,) to which the pump is attached, as from c. The tube e passes into the pump-barrel d and having a suitable piston formed at its lower end to work in the barrel d, but leaving the hole up the tube e free. A convenient form of piston is formed by screwing the pipe e to receive two nuts g and fitting with ordinary pump-leathers f between them, as shown in Fig. 1. A guide his provided to keep the tube e in a parallel line with the pump-barrel d. Any ordinary check-valve t' may be used and screwed to the piece ot' tube e, with the Valve opening upward. Into the top of the check-Valve t' I screw the rising main j, which is the pump-rod.

The pump is intended to rest on a solid bottom, and at least the strainer part c must be submerged i-n the liquid to be pumped.

It will then be seen that when the rodj is drawn upward the check-valve 1.' closes and lthe piston f draws the pu mp-barrel d full of jthisl pipe be fixed rigid at the outer end m,

the inner end fn, going up and down with the main j. From the fixed end m the water may be taken anywhere. placed in the mainj for drawing oftl by means of a valve p and as would be the case when used as an'ordinary'pump. Suitable guides may be placed to guide the pump-rod j, if desired, and the rod maybe actuated by any method giving a reciprocating action.

If it should be desired to fix ,the pump in a well in the usual manner, it may be done by attaching a base-plate to the bottom of the pump-barrel d, as' shown by dotted lines Q, in which case in place of the strainer c I use an ordinary suction-pipe and strainer to reach the water, making the pump toA x as an ordinary lift and force pump-1l. e., notself-fixing.

The above-described pump is particularly suitable for Artesian wells, for, having no solid pump-rod, it allows the use of an air vessel, which may be constructed, as in Fig. 2, with a 'chamber r and a tube u, screwed into reducing-sockets s and t, attachedto the main j, as in Figx, and placed, preferably, just above the check-valve c'.

What I claim as my invention, and desire to secure by Letters Patent, is-

In combination with a pumpand a bottom center pin or spike and a swivel or `jointed.

base-plate, and a perforated tube bolted to a lpump-barrel and a tubular piston operating in a guide at the top of the pump-barrel, and the iange-valve to convey the water upward,

Further, a T o may be IOO and the Vertical tube and top Valve, and the nam-e to this specification in the presence of' connecting-rod and the top T, for producing two subscribing witnesses. the up-and-down motion by a. Wind-motor, l and the horizontal tube fixed at its end to a. HDRLERI PLRCY SAUNDLRSON 5 Wall, substantially as described and for the VVibnesses:

pmpose specified. H. D. JAMESON,

In testimony whereof I have signed my A. NUTTING.
